A. CHA BER- LIN, a citizen of'the United States, residlng ,at Abing'ton, in the county of Plymouth and State of Massachusetts, have invented new and useful Improvements in Leather -l/Velt- Strips, of which: the following is a specification.

Thepresent invention relates to the manufacture of ribbon like strips out of leather adapted to be used for thepurpose of welting in the construction of boots and shoes, and

for'other purposes. The object of the invention is to make such ribbon or welting of leather strips which are wedge shaped in cross section, by laying such strips one upon the other with the thick edge of'one upon or against the thin edge of the other, whereby the resulting structure is of substantially uniformthickness, and oblong, or rectangular, in cross section. A further object is to make the stripsabove mentioned of short pieces or scraps of leather sca'rfed and fitted together endto end, and further to arrange the strips relatively to one another so that the joints between the pieces of one strip are intermediate. the joints between the pieces of the'other strip; in other Words, so that the pieced strips break joint with one another, although I do not limit the protec tion which I claim herein wholly to the lastmentioned feature.

The invention therefore consists in a pieced leather ribbon or welting meeting the requirements of the above stated objects, preforably constructed as described in the following specification, and having the characteristic features and principles pointed out in the claims. 7

In the drawings, Figure 1 is an elevation of a fragment of leather ribbon or welt strip made according to my invention.

Fig. 2 is a perspective view of such fragment.

Fig. 3 is a perspective view showing the elements of the ribbon dissected, and occupying approximately the relations to one another which they have in the completed ribbon.

The same reference characters indicate the same parts in all the figures.

As here shown the ribbon consists of pieces a, a and b, b all of which are of substantially uniform width, and are so beveled as to be wedge shaped in cross section. The

pieces a, a are scarfed or beveled so that they will match together at the ends and make a continuousstrip of the same cross section and thickness at the joints as elsewhere, being beveled on the under side at one end as shown by dotted lines at a in Fig. 3, and complementally beveled or scarfed on the upper side at the other end as shown at 05 The contacting scarfed surfaces are coated with cement, paste, or any other suitable adhesive before being joined together, and when thus joined they make a strip which is thick at one edge and thin at the opposite edge. Likewise the pices b, b are scarfed or beveled at opposite ends, the bevel b at one end being on the upper side of the piece and the scarf 6 at the opposite end being on the under side of the piece. These pieces are similarly coated with adhesive and joined to make a continuous strip.

The two strips thus formed are coated with adhesive, the one strip on its under surface and the other on its upper surface, and are laid together one upon the other so that the thick edge of one strip overlies the thin edge of the other, and the thin edge of the first strip overlies the thick edge of the other. These strips, or the pieces of which they are made, having been out of substantially equal width and substantially equal thickness at their thick edges, the resu1ting structure is a ribbon of substantially uniform thickness from edge to edge, that is, of substantially rectangular cross section.

In j oining the wedge strips (1, a and 6, Z) the joints in one strip may be placed intermediate or between the joints in the other strip, whereby an integral piece of leather in the adjacent strip extends across each joint, thus making an additional bond between the contiguous pieces in the same strip.

If desired the bevel of the joints in one strip may be opposite to the inclination of bevel of the joints in the other strip, as shown in Figs. 1 and 3, although this is not essential, and all joints may be inclined in the same manner.

The foregoing description of the manner in which the pieces are joined to one another into strips, and the strips united to one another, is intended only as a description of the completed article and is not in anywise a limitation as to the order of steps to be employed in making the article. Thus, for

example, it is not necessary to join all or a considerable number of the pieces a, a into a strip before uniting the two wedge strips together, but the building up of the pieces into strips and into the completed ribbon may be carried on in alternation; that is, pieces a and b may be first joined together into a section of ribbon by laying one of such pieces upon the other in the relation already described before applying additional pieces a and Z) to lengthen the strips or the ribbon; and also, if desired, the pieces a and b may be thus joined before beveling or scarfing their ends, in a manner to make relatively short sections rectangular ineross section, which are afterward beveled at the ends and joined together by placing the scarfed end of each such section upon the complementally scarfed end of the next section, with adhesive between the overlapping end parts.

By oining together a sufi'icient number of pieces in the arrangement described, a ribbon of any desired length can be made and sold or stored for future use; and from such ribbon pieces of required length may be cut as needed to make shoe welts or for other purposes.

A groove 0 may be out in either side of the ribbon near the thick edge of the Wedge pieces which form the surface in which such groove is cut. \Vhen thus grooved, the ribbon is converted into a welt suitable for use in making welt shoes of the type in which the outer sole is connected With the inner sole and upper by a welt, the interior edge of which is secured by the inseam of the shoe. The herein-described wedge shape of the between pieces in each. strip come-between I the corresponding joints in the other strip,

whereby the unbroken piece of one strip eX- tendingacross the joint between pieces of the other strip and attached to both such pieces serves as means for securing said pieces together. 7

2. A pieced welt consisting of sections each formed of two wedge shaped pieces of substantially equal width laid one upon the other with the thicker part of each extending along the thinner part of theother, and

united by adhesive; such sections beingv joined together end to end.

3. A pieced welt consisting of wedgestrips of substantially equal width laid one on the other with the thick edge of each extending.

along the thin edge-of the other and secured together, such welt having a longitudinal stitching groove in the outer surface of one of such stripsnear the thick edge thereof.

In testimony whereof I have affixed my signature.
